Abstract

A mobile sensor receives a mobile sensor location and destination. The mobile sensor determines, from a repository of road segments, a plurality of routes having a first endpoint corresponding to the mobile sensor location, and a second endpoint corresponding to the destination. The mobile sensor receives transit data from a plurality of peer mobile sensors, wherein each transit data comprises a peer mobile sensor's velocity and a peer mobile sensor's location. The mobile sensor stores at least one transit data based on the peer mobile sensor's velocity and peer mobile sensor's location corresponding to at least one of the plurality of routes, thereby forming at least one stored transit data. The mobile sensor determines that a sampling period has expired. The mobile sensor reports a route corresponding to a stored transit route having best transit data or no transit data, wherein the route is among the plurality of routes.
